Nvidia Shield Tablet K1, The Almost Identical And Less Expensive Version

At the end of 2014, Nvidia amazed us with its Android Shield Tablet, which was a huge powerhouse for the classic Google OS multimedia offering, responsive software monitoring and, above all, a solid video game strategy with an exclusive channel that turned the tablet into a real one. monster to play. After a few problems with defects erased by a prompt hardware replacement, the Californian brand renews its tablet with almost nothing to change, if not the commercial strategy.


Nvidia continues the same and starts again so that the Shield Tablet K1 succeeds the Shield Tablet. We find the same frame-based 8 inch screen “a little more than Full HD” (1920 x 1200 px on a diagonal of 20.3 cm) IPS panel, a four-core mobile chip Nvidia Tegra K1 clocked at 2.2 GHz with a 192-core graphics Kepler iGPU, 2GB RAM and expandable 16GB storage capacity by adding a microSD card. If the first Shield had a stylus, Nvidia removes it here, as well as the integrated sheath. Wi-Fi a / b / g / n / ac MIMO dual-band, GPS + GLONASS and Bluetooth 4.0 are also on the menu, as well as a photo-video sensor of 5 Mpx in the back and another of the same rank in forward. The mini-HDMI 1.4a output is still present. All is powered by a battery with a capacity of 5200 mAH and running Android 5.1 Lollipop. The primary asset of the tablet is its quality video game orientation via streaming, as for its box Shield Android TV.

The tablet Nvidia Shield Tablet K1 is marketed at € 199, € 100 less than its eldest at launch. To get there, Nvidia – in addition to the removal of the stylus – does not bother with any cable in the box, arguing that everyone now has a micro-USB cable and the appropriate sector block to charge the beast. You are warned.

To complete the concept of the tablet to play, it should be added to the Shield Tablet K1 the famous Shield Wireless Controller, which works in Wi-Fi Direct and is practical and ergonomic (see our test below).

As stated in the preamble, Shield Tablet K1 does not differ from the masses of the first grind. From the outside, they seem to be exactly the same, with the same rather basic but effective and sober design, a solid integration of connectors on a slice and physical buttons that, once again, would have deserved to exceed a little more in order to be easier to manipulate.

Structurally, the differences are as follows: the stylet disappears and its sheath into the tablet too; the coating on the back is no longer very thin rubber but polycarbonate, which makes slate slightly more slippery; the front speakers, smoothly coated on the first Shield, inherit here a rubber finish, inducing a better grip of the dish of two inches in landscape position. The edges of the front structure are also slightly better finished since the edges do not shear the fingers after a long grip.

Side heating, same topo as the Shield Tablet, the K1 has beautiful sometimes deploy power treasure, its measurable temperature never exceeds 35 ° C within a shell that allows any unpleasant feeling.


What a strange IPS screen that the Shield Tablet K1. It must already be taken into account that there are several modes of display and how to move the image. Within the basic display parameters, we thus find a complete colorimetric rendering with 3 different profiles (Native without correction, sRGB Automatic and sRGB by default), a correction of gamma, another one of the temperature and finally that of the contrast, saturation, and black level. Added to this is Prism, Nvidia’s dynamic backlighting designed to improve color and consumption. First of all, the 283 pixels per inch of density induced by the definition of the slab are well suited for most multimedia uses. These are not the 2560 x 1440 px (359 dpi) of the Samsung Galaxy Tab S 8.4, but the comfort of reading is present.

If the eldest could boast a strong contrast of more than 1100: 1, the K1 oscillates in the modes between 683: 1 and just under 800: 1. In 2015, it’s pretty average all the same. The screen can nevertheless rely on a higher brightness of 478 cd / m² (against 422 cd / m² before) and a luminous reflection of the slab of 13%, up to a Tab S 8.4. For comparison, the iPad Mini offers a record reflection of only 4%.

To obtain the best color rendering possible and even the most interesting overall color/ contrast /temperature /brightness rendering, it is necessary to disable Prism and activate the sRGB Auto mode. Any attempt to touch the many sliders invariably results in drifts and approximations. With this mode, therefore, we obtain a color rendering of good quality, with an average E delta of 3.6 and above all, a global balance sacrificed in particular by a too pronounced blue. The contrast is 699: 1. The color temperature settles in a good 6889 Kelvins very homogeneous and without affecting the image. Another flat on the board, the reactivity of the slab to touch, since the touch delay is 84 ms, in the average tablet, but very far from the excellent 34 ms Shield Tablet or 18 ms iPad Mini 4. The persistence time, it progresses, with 14 ms instead of 17 ms before.

Does this mean that Nvidia has a very correct color table, but changed the slab for the K1? No doubt, given the differences that exist today on tactile responsiveness and contrast. In itself, the screen of the K1 is quite satisfactory, but remains inherently worse than that of the first Shield Tablet and, in this, it is quite disappointing.


No software changes to note, the Tablet K1 runs, like the Tablet, in Android Lollipop version. A pure OS, with all Google tools (Gmail, Hangouts, YouTube, Drive, Play Store), but also apps dedicated to the Shield: Hub experience to open GeForce Now and Game Stream, Dabbler to draw with the optional stylus and two apps to manage the Shield controller and display on a TV (up to 4K).

Raw power monster, Shield Tablet K1 has no trouble running absolutely all the tools and uses of a classic Android tablet, but also Shield apps, the revised design, and easier access. An overpowering beast and easy to tame.

The update to Android 6.0 Marshmallow must occur before the end of 2015. When we know the promptness and seriousness that were those of Nvidia on the management of Android for the Shield Tablet, we can probably trust the manufacturer to quickly push Marshmallow.


See the Shield Tablet test for more details on video management and multimedia in general.


The audio output, quality and very high power, can power without difficulty all audio equipment. The sound is clean, with wide dynamic range and good channel separation. Only the distortion is a hair raised to full volume, but nothing fundamentally embarrassing.

The two front speakers offer a stereo sound somewhat lacking in bass but still relatively tolerable. There is no appreciable distortion.


The two photo-video sensors behave exactly the same way as on the Shield Tablet.

The rear camera only renders small services, the rendering in 5 megapixels clearly lacking sharpness, sharpness and found itself studded with noise. It is necessary, moreover, to compose with an application still not simplified, which piles the indications and the options for not much on this type of product.

The front sensor finds favor with the eyes of the conventional user for its ability to display a correct image in bright light or low light, but also and especially to the user “gamer” because of the native support of Twitch.

Playing on GeForce Now and broadcasting the content of the game and its reactions in real time live from the tablet is very fluid and easy to set up.


Endurance is not necessarily the strong point of the Shield Tablet and will definitely not be pinned to the role of honor of his K1 descendant. The slate of late 2015 thus displays and globally the same behavior. In basic use of Android tablet, the K1 offers, via our test of autonomy with viSer, a very correct running time of 10:06, a bit stronger than the Shield Tablet first name … but almost 6h less than Sony Xperia Z3 Tablet Compact. In streaming video, via Netflix, the tablet has an endurance of 8 hours, 90 minutes longer than the first Shield and about 5h less than the compact slate of Sony or the Galaxy Tab S 8.4. However, it is not here that Shield Tablet K1 actually loses points, but on its energy management when it comes to using the Shield Hub.

By launching a streaming game on GeForce Now, expect to find power after 2 hours 45 minutes, or play as much power as possible. There are subterfuges to consume less battery, such as the fine-tuning performance of the K1 chip, the activation of Prism and the adjustment of the refresh at 30 frames/second. Sometimes this will be at the expense of the overall quality of rendering, but it is at this price that we can indulge in GeForce Now for a little over 4 hours. The day before remains quite solid, with less than 10% battery in a little over 48 hours of near-inactivity, while a full charge cycle requires a little less than 3 hours.
